Soft Yoke SPM Buoy system
The single point mooring buoy with a soft yoke system includes a rigid steel frame that is connected to the buoy by means of hinges and to the vessel by means of a pendulum structure.
This requires a dedicated vessel as its hull is modified to support the pendulum structure. Typically the pendulum structure includes two pendulums that provide a restoring force when the vessel moves away from the neutral position relative to the buoy. This restoring force maximises the range of local environmental conditions in which the SPM system can moor a vessel.
Typically the soft yoke consists of a ballast weight attached to a chain or a rigid steel member with uni-joints on both ends.
The soft yoke system can also be combined with a fluid transfer system. The fluid path between the buoy and the dedicated tanker is realised by means of jumper hoses.
